note: 'A natural **SL 28** — a Kenyan variety grown in Costa Rica, which is exactly
  why it drinks like a

  Kenyan rather than like a typical Central American: blackcurrant and wild rose sitting
  on top of a

  ripe peach base. The farm has been in the Guardia family for decades and runs on
  hydro power from

  its own water turbine.


  **Why these numbers.** Naturals turn bitter when pushed, so this starts at the coarse
  end (grind 60)

  with the main pour held to 91 °C rather than the 92–93 °C a washed coffee would
  take. Hacienda Sonora

  dries its SL 28 naturals by the *Pirámide* method — the cherries are covered through
  the hottest part

  of the afternoon and then piled in layers so the temperature evens out — which is
  designed to keep the

  boozy, over-fermented edge out of a natural. Expect this one to read cleaner and
  more precise than

  "natural" usually promises, so it is worth chasing clarity rather than taming it.


  A big **60 ml bloom (4× dose) held 80 s** fully de-gasses a light, dense, high-grown
  bean, then a

  **single gentle main pour** keeps the fines down and the fruit separated — every
  extra pour muddies

  exactly the florals this coffee is bought for. RPM 120 for maximum lift. Ratio widened
  to 1:16.5 for a

  tea-like, articulated cup instead of a thick one.


  **Off? one change at a time:**


  - **Sour / thin / hollow** → reach for a longer bloom or more agitation *before*
  touching the grind.

  - **Bitter / drying / astringent** → coarser (`61`), or drop the main pour to 90
  °C.

  - **Still foaming after the bloom** → the bloom was too short; stretch it to 100
  s.'
